The specific working procedure is as follows:
when a worker needs to install an inspection well, the worker firstly finds an installed position, shovels out the soil or stones and other foreign matters at the position, shovels out a reserved space capable of containing the inspection well, then places the inspection well into the shoveled pit, inserts the joint of the pipe into the well pipe 2, enables the bag ring 4 to surround the pipe, then starts the air pump, fills air along the other end of the air inlet channel 11, then enters the expansion cavity 41 along the air inlet channel 11, and increases the air pressure in the expansion cavity 41 along with the increase of the air in the expansion cavity 41, so that the bag ring 4 is inflated under the action of the air pressure, the inner diameter of the inflated bag ring 4 is reduced, the inner wall of the bag ring 4 is abutted against the outer wall of the pipe along with the action of the inner air pressure, the joint of the well pipe is further sealed through the bag ring 4, the other end of the air inlet channel 11 is immediately blocked by the sealing plug, the air in the expansion cavity 41 is prevented from leaking, finally the cover 3 is covered on the well body 1, and the inspection well is filled with the soil or stones, so that the inspection well can be completely removed from the well pipe 4, and the inspection well can be replaced by only by pulling down the pipe 4, and the inspection well can be completely replaced by the inspection well, and the inspection well can be completely replaced by the device when the pipe 4 is required to be replaced by the inner wall of the inspection well, and the inspection well is only by the inner wall is required to be completely replaced by the pipe 4, and the inspection well is only is required to be completely by the inner well, and the pipe is required to be completely and the pipe by the pipe is replaced;
the air pump can be replaced by the pressure regulating component 5, when a worker pulls a pipeline to the inner side of the bag ring 4 of the well pipe 2, the worker only needs to press the pressurizing block 53 in a manner of stepping on or pressing by hand and the like, the pressurizing block 53 slides along the pressurizing block 52 near the bottom of the pressurizing block 52 after being pressed, gas in the pressurizing block 52 opens the second one-way valve 57 to enter the other end of the air inlet channel 11 under the extrusion of the pressurizing block 53, and finally enters the expansion cavity 41 along the air inlet channel 11, so that the bag ring 4 is expanded, when the worker releases the pressurizing block 53, the pressurizing block 53 moves away from the bottom of the pressurizing block 52 along the pressurizing block 52 under the action of the spring 54, negative pressure is formed in the movement process, so that external gas enters the pressurizing block 52 along the air inlet hole 55, the first one-way valve 56 is replenished with the gas in the pressurizing block 52, then the worker repeatedly presses the pressurizing block 53 again, the purpose of pressurizing the gas in the expansion cavity 41 is achieved, and when the gas in the expansion cavity 41 needs to be depressurized, only the J-shaped rod 59 is pushed to slide along the sliding groove 58, so that the first one end of the second one-way valve 59 is far away from the bottom of the pressurizing block 52, and finally the air inlet channel 52 is opened along the expansion cavity 52, and the air inlet hole 55 is contracted, and the one end of the self-way valve is opened, and the air inlet channel is opened along the expansion cavity 41, and the one end of the expansion valve is opened, and the air valve is opened, and the one end of the air valve is opened;
the sectional shape of the chute 58 is set to be circular, so that when the inspection well is used, the short end of the J-shaped rod 59 is downwards under the action of gravity, the short end of the J-shaped rod 59 is staggered with the air inlet hole 55, and therefore, even if the J-shaped rod 59 slides anyway, both ends of the J-shaped rod 59 can not contact the first check valve 56 and the second check valve 57 under the obstruction of the outer wall of the pressurizing block 53, and the bad consequences that the first check valve 56 and the second check valve 57 are opened due to the fact that the J-shaped rod 59 is driven by foreign matters to slide are prevented, and finally, the air pressure of the expansion cavity 41 is relieved are caused; when the first check valve 56 and the second check valve 57 are required to be opened at the same time, only the J-shaped rod 59 is required to be rotated, so that two ends of the J-shaped rod 59 are aligned with the first check valve 56 and the second check valve 57 respectively, and then the J-shaped rod 59 is pushed to slide along the sliding groove 58, so that the first check valve 56 and the second check valve 57 can be opened, and when the well lid 3 is closed at ordinary times, the air inlet hole 55 is blocked by the plug;
wherein, in the process that one end of the pipeline enters the well pipe 2, the outer wall of the pipeline is contacted with the elastic sheet 6, and the elastic sheet 6 can scrape the outer wall of the pipeline, so that impurities on the outer wall of the pipeline fall off under the scraping action; when the pipeline stretches into the well pipe 2, the elastic sheet 6 is bent on the outer wall of the pipeline, the pressure regulating assembly 5 is used for expanding the bag ring 4, a part of the expanded bag ring 4 can press the outer wall of the pipeline through the elastic sheet 6, and after the no-building inspection well device is installed, the friction force between the outer wall of the pipeline and the elastic sheet 6 with the anti-slip strips 61 needs to be overcome when the pipeline is pulled by the pulling force; the elastic sheet 6 is extruded by the bag ring 4 after being bent, so that one surface of the elastic sheet 6 is attached to the outer wall of the pipeline, the other surface of the elastic sheet is attached to the outer wall of the bag ring 4, and the friction force between the bag ring 4 and the elastic sheet 6 is increased through the arrangement of the clamping strips 42 and the anti-slip strips 61 on the inner side of the elastic sheet 6; the two well pipes 2 are connected through the bag pipe 7, so that impurities such as sludge and sewage are remained in the well body 1 as much as possible.
